Abstract

PURPOSE:To strengthen the engaging force of the engagement head so as to resist sufficiently a horizontal pull by forming the cross section of a curved portion forming an approximately semi-circular shape spreading toward the end an inside from a projecting portion of the head of the engagement, and by approaching or abutting the horizontal parts to each other. CONSTITUTION:The inside of an engagement head 6 bends a mono-filament (m) having a circular or oblong cross section at a reverse bending part from an upper arm 2. Each cross section of part bending to the part or to the lower arm 3 provides bending parts 8, 9 deformed in an approximately semi-circular configuration spreading toward the end with each horizontal peripheral part 10, 11 facing with each other in approaching and contacting state. With such a construction, the engaging head 6 is made to be pushed to a projecting part 5 with the body of the filament at the inside of the engaging head being pressed. The configuration of the projecting part 5 becomes a swelled mountain-like shape having a smooth slanting face. Consequently the engaging area increases, making the part thicker to strengthen the base of the engaging part. Therefore even when considerably strong horizontal pull is applied to the engaging part, the chain will not break.

って急な流れを呈するものである。The interlocking head formed on conventional continuous fastener elements of this type is formed by stamping monofilament, or by crushing the monofilament by using the force when it is wound around a mandrel whose cross section is approximately flat. In both cases, the protrusion of the interlocking head is formed by moving the flesh of the monofilament, and examples of this are shown in Figs. 7 and 8.
The engaging head 12 of the continuous fastener element is thin, and the slope I4 leading to the protrusion 13 is constricted and exhibits a steep flow.

噛合している時の横引き係合力に今一つ信頼性かなく、
噛合時にあるいは噛合状態において強い横引力を受ける
と、噛合頭部の噛み合いが外れてチェーン割れ現象を起
こす問題があった。As mentioned above, in the conventional engaging head, the slope forming the protruding part is constricted, and this is formed into a gentle or convexly curved surface, as shown by the two-dot chain line in Fig. 8, for example. However, many of the conventional ones have a surprisingly deep constriction, so the engaging area is small and the walls are thin, so the horizontal pull when the fastener elements are engaged is difficult. The resultant force is not very reliable,
When a strong lateral attraction force is applied during or in a meshed state, there is a problem in that the meshing heads become disengaged, causing a chain cracking phenomenon.

本発明は上述の問題を解消して、強い横引力に対しても
十分に耐えることができる係合力の強い噛合頭部を有す
る連続ファスナーエレメントを提供することにある。The present invention solves the above-mentioned problems and provides a continuous fastener element having an engaging head with a strong engagement force that can sufficiently withstand strong lateral pulling forces.

くは当接する状態に対面していることを特徴とする。The solution according to the present invention is that, in the engaging head of a continuous fastener element for a slide fastener formed by bending a synthetic resin monofilament, the cross-sectional shape of the bent part forming the inner side of the protruding part of the engaging head becomes wider. It is characterized by having a substantially semicircular shape, with the horizontal sides of the bent portions facing each other in a state of being close to or in contact with each other.

のである。Since it has the structure described in the previous section, the shape of the protruding part of the engaging head is a plump mountain shape with a gentle slope, and the engaging area of the engaging head is expanded and the thickness is increased. This allows the engagement force of the meshing portion to be increased considerably.
